    So i got this idea to use a couple of scissor jacks for a low cost 1 or 2Dof on my P1x rig. They really dont take much torque to lift and are close to free. Since the rod does move up and down a bit i'de either mount the motor on a frame that moves with it or use an Ujoint.

    I got a 12v wiper setup and some rotary encoders that id like to use for testing but im wondering how i would do that. Is it possible to modify to SMC3 sketches for encoders rather that pots or do i need something else? Im also thinking about doing a gear box given that the motors are only 60 rpm but its more of a proof of concept at this point and depending on torque needed you might be able to get some high rpm low cost motors.

    Perhaps something along the lines of this electric one

    Got some very cool idea's in there i can use that may let me get away with a normal 360/180 pot using levers. I did a quick test and there's very little force needed to lift it even at aprox 130kg so i can easily make a 2 Dof with wiper motors and some help from some springs if needed. Ill update on the progress!

    Been doing some more testing and ideas are flying hehe. I can actually make a 4 motor setup that works very well with levers! I knew these heavy duty springs i found at a field will come in handy some day!

    With a metal nuth you could get galling problems.
    Hope it works.
